Mounting instructions for the displacement encoder MLO-POT-...
 Always mount the displacement encoder and cylinder symmetrically, if possible (middle of the meas
uring system stroke must match the middle of the entire cylinder stroke).
For the displacement encoder MLO-POT-..., an electrical reserve of ≥ 0.3 % of the nominal length is re
quired in both end positions so that a wire break or defective wiper can be detected (already taken into
account with the integrated potentiometer of the DSMI).
Example:
Nominal length of the displacement encoder: 1000 mm; electrical effective length: approx. 1006 mm
} Permitted work path: 0 ... 1000 mm
If the displacement encoder slide leaves the permitted work path, the CMAX generates a corresponding
error message. To avoid these error messages:
 Limit the positioning range so that the displacement encoder slide is always within the permitted
work path.
